ENVELOP.

Specification of Letters Patent.

Patented Aug. 24, 191 5.

Application filed May 6. 1915. Serial No. 26,210.

To all whom it may concern Be it known that I, GEORGE W. SWIFT, J r., a citizen of the United States, residing at Bordentown, in the State of New Jersey, have invented a certain new and useful Improvement in Envelops, whereof the following is a specification, reference being had to the accompanying drawing.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawing :-Figure I is an elevation of a plane blank from which an envelop embodying my invention may be formed. Fig.

II is an elevation of said blank as prelimi-- narily creased, foldedand provided with adhesive. Fig. III is an elevation of the envelop formed from the blanks shown in Figs. I and II with the flap'at the upper longitudinal edge thereof open to permit the insertion of mail matter, and with the left hand end open for inspection of such matter. Fig. IV is an elevation of said envelo'" with the flap closed at the upper. edge thereof and the left hand end flap turned out for inspection of the contents. I

Referring to Fig. I; the plane blank 1,

whi h may be formed of paper or any other suitable fabric, has its lower left hand corner 2 perforated with the line 3 where it may be subsequently severed. Referring to Fig. II; said blank 1 is creased at the lines 5, 6, 7 and 8, folded at the line 8, to form the inwardly turned inspection flap 10, and providedvwith the adhesive 11 at its corner 2 within said perforated line 3, and said blank 1 also has its upper longitudinal sealing flap 13 provided with the adhesive 15, and its transverse end sealin flap 16 provided with the adhesive 1 Referring to Fig. III; said blank 1, ro vided with adhesive, as above describe is then folded on the line 7 so that its rear wall 19 is attached to its front wall 20 by the adhesive 11 on said flap 10. Said blank is then folded on the line 6 so that the flap embodided in envelops of the 16 overlaps said rear wall 19, upon the back thereof, and is permanently sealed thereto. Of course, when the envelop is thus com pleted, it is closed at the right hand end and open at the left hand end, from the bottom up to the edge of the adhesive 11 on said flap 10, and, consequently, when the envelop is sealed by folding the flap 13 on the line 5 and causing said flap to adhere to the rear wall'19 by the adhesive 15, its interior may be inspected through its open left hand end, without turning out said inspection flap 10, and, said flap secures the contents of the envelop against accidental escape from said open end. However, if it is desired to thoroughly inspect the contents of the envelop by withdrawing the same through said open end, said flap 10 may be turned outwardly as indicated in Fig. IV; the act of turning it out severing said flap along the line 3 as indicated, and leaving the corner 2 adhering to the front wall 20 of the envelop. It may be observed that said flap is rendered readily accessible to the finger of the operator, and its outward turning movement aforesaid facilitated, by having the upper end of the flap cut off at an angle oblique to the end of the envelop and intermediate of the extent of the opening thereat. After such inspection, saidfiap 10 may be returned inwardly, from the position shown in Fig. IV to the position shown in Fig. III, but, of course, without reconnecting the corner 2 with said flap. However, as said flap 10 extends across the line 7 at the bottom fold of the envelop, unbroken and im )erforate, it is securely held against acci ental outward displacement when it is inwardly folded, both initially and when returned after inspection. It ma be observed that the purpose and effect 0 said adhesive corner 2 is to not only hold the front and rear walls of the envelop together at the normally open left hand end of the envelop shown in Figs. III' and IV, until they are secured together by the adhesive flap 13,

but to normally restrict the opening in said end to less than the distance from the top to the bottom edge of the envelop, and thus prevent withdrawal of any contents of the envelop of that extent, until said corner is severed.

It is not essential that my invention be articular form which I have chosen for il ustration. Therefor, I do not desire to limit myself tothe p'recisedetails of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.
